KIT expression

IGF2BP3 knockdown increased ovarian cancer sensitivity to sorafenib. This study confirmed that IGF2BP3 knockdown inhibited ovarian cancer cell malignancy, promoted ferroptosis and inhibited autophagy-mediated EMC2 degradation, and verified that IGF2BP3 knockdown increased the sensitivity to sorafenib in ovarian cancer mice.

This case expands the morphologic and immunophenotypic spectrum of PFM and indicates the possible diagnostic utility and biological significance of D2-40 expression. Although molecular confirmation of MALAT1::GLI1 fusion is definitive for the diagnosis of PFM, the findings of the present case may aid diagnosis in challenging cases that mimic GIST.

Palliative therapy with toceranib phosphate and meloxicam achieved prolonged survival and excellent quality of life, with no adverse effects despite dose escalation...The observed benefit likely reflects toceranib's multi-target activity (VEGFR2, PDGFR), impacting angiogenesis and tumour progression. This case represents the first report of toceranib phosphate use in feline pulmonary carcinoma and underscores its potential as a palliative option.

Here, we summarize current knowledge of KIT expression and the functional consequences of Kit mutations, with particular emphasis on oocytes across ovarian cell populations and in comparison to other organ systems in humans and mice. We further evaluate the physiological and pathological significance of ovarian KIT signaling in female fertility and highlight crucial knowledge gaps that must be addressed to fully elucidate its role in maintaining ovarian function.

These findings support a shared pathogenic mechanism between Smith-Magenis syndrome and Birt-Hogg-Dubé syndrome, contributing to the existing literature on FLCN-associated renal neoplasia. Recognition of this overlap is important for clinical awareness and further supports renal surveillance in Smith-Magenis syndrome patients.

MCT dogs having TP53 c.659 T > C were 1.65 times higher hazard risk on decreased time to recurrence by univariate analysis (95% CI 1.02-2.67, P = 0.041), but not in multivariate analysis. Our study suggests that SETD2 c.1108_1109del, and TP53 c.659 T > C may associate with poor prognosis; however, further study with larger samples is needed to confirm these correlations.

These findings indicated that quercetin exerted a protective effect against ARHL by suppressing NLRP3 inflammasome activation and modulating mitophagy, providing a theoretical basis for applying quercetin to treat ARHL.

Notably, residual mRNA CAR T cells following AML clearance showed no detectable CAR expression and preserved HSPC colony-forming capacity. Our in vitro studies suggest the potential use of mRNA CD117 CAR T cells as a non-genotoxic preconditioning strategy for patients with high-risk or refractory AML.

High-risk patients had immunosuppressive TME and poor immunotherapy response, with Imatinib/PLX4720 showing potential efficacy. CD36/KIT overexpression promoted GC malignancy; their inhibition remodeled TME cytokines and, for the first time, activated the PA pathway to induce GC cell death.

Histopathologically, syringomatous tumor may resemble cutaneous adnexal tumors, particularly syringoma and microcystic adnexal carcinoma, and breast carcinomas. However, in addition to the clinical appearance and location, the presence of a peripheral myoepithelial lining and immunoexpression of SOX10 and c-kit may help exclude these entities.

Increased c-kit expression, along with reduced beta-catenin expression in endometriosis samples, suggests that these molecules contribute to endometriosis pathogenesis. However, because no significant difference was found in E-cadherin expression, a definitive conclusion cannot be made regarding the involvement of E-cadherin in endometriosis development.

These tumors express diagnostic GIST markers (c-Kit and DOG1) and show significant response to the BRAF inhibitor dabrafenib. This model recapitulates key histopathological and molecular features of human BRAF-mutant GIST and provides a valuable platform for studying tumor initiation, progression, and therapeutic resistance. Importantly, it allows for preclinical testing of targeted therapies in BRAF GIST, offering new insights into treatment strategies.
